Direct Palladium-Catalyzed Arylation of Cyclopropenes

Journal of the American Chemical Society, 2005
The first examples of direct palladium-catalyzed arylation and heteroarylation of cyclopropenes have been demonstrated. This method allows for efficient synthesis of various tetrasubstituted cyclopropenes, incuding nonracemic cyclopropenes, which are not available via known asymmetric cyclopropenation methods.

Palladium-Catalyzed Direct Arylation of Aryl(azaaryl)methanes with Aryl Halides Providing Triarylmethanes

Organic Letters, 2007
Direct arylation of aryl(azaaryl)methanes with aryl halides takes place at the benzylic position in the presence of a hydroxide base under palladium catalysis to yield triarylmethanes.

Copper-mediated direct arylation of benzoazoles with aryl iodides

Tetrahedron Letters, 2008
Abstract The direct arylation of 1,3-benzoazole compounds with aryl iodides is effectively promoted by CuI with use of PPh 3 and Na 2 CO 3 or K 3 PO 4 as ligand and base, respectively, in DMF or DMSO to produce the corresponding 2-arylated products with good yields.

Direct arylation of azine N-oxides with aryl triflates

Tetrahedron, 2009
Palladium catalyzed direct arylation of azine N-oxides using aryl triflates to afford the corresponding 2-aryl azine N-oxides is described. The reaction is carried out with a range of both N-oxides and aryl triflates. The arylation can be carried out in sequence to yield differentially diarylated products.

Intramolecular direct arylation

2018
The research conducted for this thesis has led to the development of an intramolecular gold-catalysed direct arylation protocol whereby tethered arenes and aryltrimethylsilanes are coupled (Scheme 1). In Chapter 1, the key synthetic and mechanistic studies that have ultimately led to the conception of this project are introduced.
